Didnt someone say that they did a comparison between a spoon style duct vs. stock box and that 1st gear was the same and then the spoon style duct-s2ooo started to pull away once in second?

 

i found a dyno for a aem and an injen and the injen produced more hp and torque throughout the rev band i guess thats due to the larger piping of the injen i believe 3in and aem 2.5-2.75 not sure he is the chart:

This topic has been beaten to death. The two intakes are identical with one exception: AEM is two piece, Injen is one piece. Those dynos were originally posted in this thread:

Ultimate Lurker showed the flaw in the testing methodology that gave Injen slightly higher results:
Based upon R&D's response, I have to say that these two intakes are pretty much identical. The first run you do after any down time on a dyno needs to be a throw away. Operating temps are uncertain as is engine behavior. If you'll note that both intakes performed almost identically on their 2nd runs.

AEM from 3.5k MAX HP 210.4 TQ 140.1
INJEN from 3.5k MAX HP 210.2 TQ 139.5

I'll bet the graphs are similar too. This is the only safe way to compare since engine conditions are likely to be more similar on the 2nd run. The fact that there was such a variance between runs 1 and 2 for each intake tells me that conditions were not stable on the first run.

 

I wasnt asking between AEM and INJEN. I wanted to know between the INJEN or the SPOON Ram Air Kit. I have seen dyno charts of the INJEN but not the SPOON, so maybe someone knows or can suggest.

 

If you guys are saying GO-INJEN over the AEM based on looking at the dynos, you guys are also at the same time splitting hairs and basically paper-chasing.

Don't expect too much gain from any CAI on our cars. The AEM/INJEN most definitely changes the "feel" and sound of the car. I didn't like the way it changed the nature of the revs so I dumped mine.

To the original poster: if I were you, I'd go Spoon.

Stock airbox is mysteriously a solid intake for the S2000.

Good luck.

 

Dyno gains of the INJEN are pretty much apparent. There are no dyno gains for the Spoon, since the Spoon does nothing to change the stock intake system except for possible better air delivery into the system at speed and keeping intake air cool. I have read that the Spoon does not restrict intake enough to cause loss on dyno as well.

 

"I was pulling simple pressure readings from just inside the horn of the air box. At 75 to 85 mph and no acceleration it would spike to 10 psi, under heavy acceleration it dropped to about 3 or 4 psi".

TPN....no such thing as a "simple pressure reading" in a vortex area.

Please provide specifics. What was the specific pressure gage used (make, model and where attahced)? What was the charge amplifier used (make and model)? And how did you reduce the data (specific program)?


If you can't answer these three basic technical questions............

 

Alright guys thanks for the help!

 

just on a side note:

Spoon/Import Development style intakes are cold air DUCTS for the stock air box.

AEM/Injen style intakes are replacement cold air intakes.

Spoon/Import Development ducts are proven NOT to lose power, but it makes no power on the dyno - I don't feel dyno is everything, but everyone is entitled to their opinions.

People choose their own mods for various reasons - I didn't like the top end feel of the AEM, but that's just my opinion. A few people who have purchased the cold air ducts have expressed their concerns over dealer hassles on mods, and the cold air ducts can be removed in less than 1 minute. Some people prefer the ease of filter cleaning/replacement, some said they believed in Spoon's racing heritage.

If you're looking for "power gains" that can be felt, AEM/Injen style no doubt - but there are reasons why tuners like Mugen and Spoon don't use that type of intakes.
